Radialstrahler 111 F

MBL’s eye-catching speakers share more than avant-garde design. Every one of our handcrafted transducers uses MBL’s exclusive omnidirectional tweeter and midrange drivers. These pulsating, spherical membranes are composed of the same exotic carbon-fiber material found in our Flagship 101 X-Treme and the iconic 101 E MKII.

The four-way MBL 111 F low-mid is handled by a pair of 5.5” aluminum cone drivers mounted in a push-push configuration on either side of the decoupled cabinet. Housed in a sealed 14 L enclosure, the proprietary internals deliver a tight, well-controlled low-mid that cleanly blends into a unique, three-dimensional soundscape.
